分享[数据挖掘醒目]请教高手们几个概念题，救命！！！！
小弟正在学习数据挖掘的相关知识。。。老师留了几个概念题实在是让我一头雾水，希望高手们能抽出点时间帮我解答一下。。万分感谢！！！
这些题都是先判断对错然后再给出判断的详细理由。
1.Taking warehoused data as a starting point is beneficial for data mining tasks.
2.Data mining projects presuppose that data warehousing infrastructure is in place.
3.Data warehousing and data mining are alternative technologies.
4.A valid and novel pattern is ,therefore,useful.
5.The knowledge discovery process(KDD) must include an understanding of context and culminate in deployment.
6.The nature of datamining tasks requires tackling a trade-off between effectiveness and efficiency.
7.Data description and summarization are not considered inherent to the KDD process.
8.Choosing a data mining technique is strictly determined by the expected output.
9.Language bias alone cannot determine which patterns are discovered.
10.The language bias is more determinant than the search bias.
11.Too strong a search bias can compromise the effectiveness of the knowledge discovery process.
就这么多，高手们一定要帮帮忙啊。。不然我就死定了。。。再次感谢！！！
